<h1 class="topictitle1">Adding group references</h1>
<div><p>A group reference is a declaration that references a group. It
enables the referenced group to appear in the instance document in the context
of the referencing declaration.</p>
<div class="section">The menu option to add a group reference only appears if there are
groups defined elsewhere in the document.<p>The following instructions were
written for the Resource perspective, but they will also work in many other
perspectives.</p>
<p>To add a group reference, follow these steps:</p>
</div>
<ol>
<li class="stepexpand"><span>In the Design view, right-click the content model you want to work
with and select <span class="uicontrol">Add Group Ref</span>.</span></li>
<li class="stepexpand"><span>Select the new group reference.</span></li>
<li class="stepexpand"><span>In the Properties view, select the group you want to refer to in
the <span class="uicontrol">ref</span> list.</span></li>
<li class="stepexpand"><span>Click the <span class="uicontrol">Documentation</span> tab if you want
to provide any information about this group reference.</span> The <span class="uicontrol">Documentation</span> page
is used for human readable material, such as a description.
</li>
<li class="stepexpand"><span>Click the <span class="uicontrol">Extensions</span> tab if you want to
add application information elements to your annotations of schema components.</span>
The <span class="uicontrol">Extensions</span> page allows you to specify the
schema and add XML content to your annotations.</li>
